Information Communication

This text discusses the different levels of detail required for information transmission, from the physical layer to the application layer. It also provides an example of a bandpass filter that can be used to filter signals on transmission lines.

Questions

1. What are the different levels of detail required for information transmission?
2. What is a bandpass filter?
3. How can a bandpass filter be used to filter signals on transmission lines?

Answers

1. The different levels of detail required for information transmission are:
• Physical layer
• Data link layer
• Network layer
• Transport layer
• Session layer
• Presentation layer
• Application layer
2. A bandpass filter is a type of filter that allows frequencies within a certain range to pass through while blocking frequencies outside of that range.
3. A bandpass filter can be used to filter signals on transmission lines by setting the filter’s bandwidth to the desired frequency range. This will ensure that only signals within the desired range are transmitted, while signals outside of the range are blocked.
